The Chauri Chaura incident took place on 4 February 1922 at Chauri Chaura in the Gorakhpur district of the United Province (modern Uttar Pradesh) in British India, when a large group of protesters participating in the Non-cooperation movement, clashed with police who opened fire. In retaliation the demonstrators attacked and set fire to a police station, killing all of its occupants. The incident led to the death of three civilians and 22 policemen.
Mahatma Gandhi, who was strictly against violence, halted the non-co-operation movement on the national level on 12 February 1922, as a direct result of this incident. In spite of Gandhi's withdrawal, 25 freedom fighters died due to revenge jurisdiction by British.
